Casinos are another high frequency trading environment where everything needs to be rock solid. If that's the sort of background you have then keep us posted.
The casino is pretty solid, loss of coin, hacking, DDOS, too much traffic too fast etc have all been accounted for. The version is still beta however, should a failed payment occur we will handle it to the best of our ability to resolve the situation as fast as possible.
Once the server throws an exception it is logged and an SMS is sent to my "work" blackberry, so far this hasn't happened once, we do however verify every transaction larger than a set amount of dollars with more than zero confirmations as faking (e.g. double spending) transactions becomes profitable and we fetch the prices from Gox for this purpose, once their server has crashed it has notified us of that and has started using another exchange as a source, this was logged as an unimportant exception which is unworthy of an SMS basically.
You can try the casino yourself, as for the exchange the idea is a little bit different than Gox so I am not going to elaborate on that but security wise we would have to be superior to most commercial banks, e.g. custom written bitcoin server, java powered website, properly encrypted and stored data, someones needs to take control over this billion dollar market.
I feel very happy all those problems are happening now and not later. I think the DDoSers are playing their cards too soon, but this is what you get when the crooks don't have a vision for a long con game and would help people like you invest in a better, proper solution for the network, now or sooner than later.
I am not a player but watching that video feed live was really fun. Maybe you could have live feeds for other sports (horse races, dog races, etc, etc).
